Walker works in porcelain to create pieces that explore ideas of growth and decay through the construction and layering of complex surfaces. All of her pieces start by being thrown on the wheel, before being built upon with thousands of individually applied fragments of porcelain. Many of her pieces are thrown and altered, often being cut away and reassembled in the leather-hard stage which allows her to deconstruct the form creating new surfaces on which to continue adding her porcelain layers.
